Java错误-实际参数和形式参数列表的长度不同 [英] Java Error - Actual and formal argument lists differ in length

问题描述

我正在尝试调用一个方法，但是它给出了这个错误:

I am trying to call a method, but it is giving this error:

java:112:错误: 必填:字符串，字符串

java:112: error: required: String, String

发现:字符串

原因:实际参数和形式参数列表的长度不同

reason: actual and formal arguments lists differ in length

这是我要调用的方法:

public void setShippingDest(String inCustName, String inDestn) {
    // ...
}

这就是我要称呼它的方式:

Here is how I'm trying to call it:

shipOrder.setShippingDest("Broome");

推荐答案

很简单.这是setShippingDest的声明:

public void setShippingDest(String inCustName, String inDestn)

这就是您要如何称呼它:

And here's how you're trying to call it:

shipOrder.setShippingDest("Broome");

您提供了一个参数，但是有两个参数?您希望它如何工作?您要么需要提供另一个参数，要么删除一个参数.

You've provided one argument, but there are two parameters? How do you expect that to work? You either need to provide another argument, or remove one parameter.

(我也强烈建议您从所有参数中删除in前缀，并考虑使用真正的单元测试框架(例如JUnit)，而不要编写大量的main方法.)

(I'd also strongly advise that you remove the in prefix from all of your parameters, and look into a real unit testing framework such as JUnit, rather than writing an enormous main method.)
